    Ok, so here's the story. Playing, went to adjust my blend pot and all I got was a middle finger and dead bass. Opened her up, had two disconnected wires with a bit of shrink tubing on it, no signs they were ever connected and one that looked like it broke off. Took it to the repair shop thinking a quick solder job and I would be on my way. They were stumped. The main issue is that they felt it came stock with a push pull selector pot. While I didn't buy it brand new, the previous owner stated he had it stock, and judging by the apparently stock strings, I trusted him.

    Repair shop states they can get it soldered passively with the pot that was in there and it worked passively. And when they attached the push pull pot that they wanted to they got no sound. He also complained my tapewounds created a really soft sound, so I am wondering if there is any bias there.

    Any thoughts?

    Anyway, those pickups can be used (they're passive) in a standard VVT or VVT-Switch schema. I did it long long time ago, later I sold the bass, and I remember the bass more usable in passive mode. Anyway in the URL above you have at least a pair or options. Greetings!

    Bumping this, I just picked up a 2009 Epi Thunderbird Pro IV secondhand. Love everything about it except the electronics. I, too, am getting an annoying buzz!! I can't find any loose wires in the control cavity, but the buzz gets a lot less if I put my hand on the input jack or turn the Treble all the way down. I've seen a lot of posts about this, but most end up with "I returned it and got a new one". Not an option for me. Although shielding the control cavity and pickup cavities may help suppress the noise, I don't think that's the real answer. Anyone get rid of this noise for good?
